PLANER.

Specification of Letters Patent.

Patented May 9, 1916..

Application filed October 5, 1915. Serial No. 54,247.

To all whom it may concern:

Be it known that 1, WILLIAM A. BRIDGES, a citizen of the United States, residing at Monett, in the county of Barry and State of Missouri, have invented certain new useful Improvements in Planers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to planers, and has for its primary object to provide a novel and efficient planer of the rotary cutter element type embodying certain novel features of construction designed to facilitate quick and convenient adjustment of the rotary cutter element.

With this and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 represents a side elevation of the improved rotary planer, partly in section, Fig. 2 represents a central sectional view on the line 2-2 of Fig. 1, Fig. 3 represents a top plan view of the planer, and Fig. 4 represents a detail longitudinal sectional View, partly broken away, illustrating the adjusting screw for the rotary cutter elements in detail.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral ing or housing having an open lower end secured at its forward and rear extremities to a pair of supporting or base members 6. A pair of partitions 7 are arranged within the casing walls of the latter and between which is supported a. suitable type, of electric motor 8. the lead wires 9 of which project through an aperture in the dome or upper portion of the casing 5'. The shaft 10 of the motor 8 projects through and is rotatably supported in the upper portions of the partitions 7., and in the spaces between the partitions 7 and the side walls of the casing 5 relatively large gear wheels 12 are non-rotatably secured upon the shaft 10. A pair of intermediate gear wheels 13 are amanged below and rearwardly of the gear wheels 12, mesh with the latter and are non-rotatably secured to and 5 indicates a cas.

5 in spaced relation to the side the opposite extremities of an intermediate shaft 14, which latter is supported in adjustable bearings or cross heads 15 engaged in slots 16 formed in the partitions 17 and being curved from end to end concentrically with the shaft 10 of the motor 8. To insure permanent and accurate meshing of the gear wheels 13 with the gear wheels 8, the shafts l0 and 14 are pivotally connected by a pair of arms 18.

An adjusting screw 20 is fitted in an internally screw-threaded aperture 21 formed in the rear wall of the casing 5 substantially in alinement with the arcuate slots 16 in the partitions 7. The outer extremity of the screw 20 is provided with a handle 22 and the inner or forward extremity thereof is rotatably secured in a collar 23 rotatably mounted upon the shaft 14, whereby the latter may be adjusted forwardly and rearwardly in the slots 16.

Adjacent their lower edges the partitions 7 are formed with vertically elongated slots 24 arranged in-vertical alinement with the drive shaft 10 of the motor and receiving a pair of vertically adjustable cross heads or bearings 25, in which is supported a tool shaft 26. Gear wheels 27 are keyed to the opposite extremities of the shaft 26 and are retained in permanent mesh with the intermediate gear wheels 13 by a pair of arms.28, pivotally connecting the shaft 26 with the intermediate shaft 14.

A preferred type of rotary surfacing element, designated generally by the numeral 30, is non-rotatablv secured upon the shaft 26 between the partitions 7 In the practical use of the planer the r0- tary surfacing element 30 may be adjusted vertically by simply adjusting the screw 20, which latter moves the intermediate shaft 14 and effects a vertical movement of the tool shaft 26 through the pivoted arms 28.

What I claim is:

1. A planer including a casing, a vertically adjustable tool shaft rotatably supported in said casing, an intermediate shaft rotatably mounted in said casing, driving connections between said intermediate and tool shafts, arms pivotally connecting said shafts, and means for adjusting said intermediate shaft.

2. A planer including a casing, a tool shaft rotatably supported in said casing and adjustable vertically therein, an adjustable intermediate shaft rotatably supported in said casing, means for adjusting said intermediate shaft, and a palr of arms plvotally connectingsaid shafts.

A planer including a casing, a motorsupported in the upper portion of said casmg, an intermediate shaft adjustably supported in said casing, driving connections between said intermediate shaft and said motor, means for adjusting said intermediate shaft, a tool shaft adjustable vertically of said casing, and means connecting said intermediate and tool shafts.

4. A planer including a casing, a motor supported in the upper portion of said casing and including a shaft, an intermediate 15 shaft rotatably and adjustably supported in said casing below said motor, means for adjusting said intermediate shaft, permament driving connections between said motor and intermediate shafts, a tool shaft, and a 2( pair of arms pivotally connecting said intermediate and tool shafts.

In testimony whereof I affix my signature in presence of two Witnesses.
